Fix Recommendation

Modify "/etc/fstab" to use the "nosuid" option on the "/dev/shm" file system.

Check Contents

Verify "/dev/shm" is mounted with the "nosuid" option with the following command:

$ mount | grep /dev/shm

tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,seclabel,size=2097152k,inode64)

If the /dev/shm file system is mounted without the "noexec" option, this is a finding.
